Beachrocks at different locations along Rio de Janeiro coast (southeastern Brazil) play an important role in the understanding of coastal evolution and sea-level fluctuations in the Holocene. The studied area presents a long and wide stretch of coastal plain characterized by two sandy barriers, which confine a series of small isolated chain-like lagoons in addition to large lagoons on the reverse side of the inner barrier. The beachrocks occur at different positions in relation to present-day mean sea level. These can be observed as submarine outcrops and along the beaches. The 8.100 years old B.P. beachrocks reveal a phase of retr...
